"Where are you coming from now?" Is this English? Why not "From where are you coming now?"
Of course it's English. There is no reason that you cannot end a sentence with a preposition.
"Where are you coming from now?" sounds more natural to me, an Englishman, than "From where are you coming now?"
"From where are you coming now?" sounds like something written by someone who has learned English from books. It is grammatical but something I only hear said by pedants and native speakers who are poking fun at pedants.
Good choice! :) The word ended up as «suburra» in Italian, and now means "slum" in Italian. For curious students, Subura/Suburra was a down-at-heel area in Ancient Rome, apparently it was very seedy, its dwellers lived in «insulae», kind of cheap apartment buidlings with «tabernae» on the ground floor. The ancient equivalent of living in an apartment building with a hostel or shop on the ground floor!: https://en.wikipedia.org/wiki/Suburra
